Connector provides high-current (up to 0.5A) dc-coupled 5V output and optoisolated I/O. When optoisolated pair is used used as an input (common use), external signal is applied between XSYNC1 (+) and XSYNC2(-). When the pair is used as an output (less common), external 5V power source should be connected in series with the receiver and 103891, so that "+" will be applied to XSYNC2, and "-" - to XSYNC1 (opposite to the input mode). Details are available in the circuit diagram of the 10389 board.
Output synchronization can be just a pulse or carry additional timestamp data when used to synchronize multiple NC393 cameras. See Trigger_393 for the settings.
